Title: Remove * {filter:none} from media print due to IE9 repositioning and float issues

In combination with html form input tags, having float:left style applied, Modernizr 2.0.6, IE9 and PIE-1.0beta6 (for rendering CSS3 properties in IE) the setting of "filter:none" causes the input elements to disappear. See it for yourself (in IE9):

Or when you haven't got IE9 at your disposal:
